Title: Processor-to-processor communications protocol for a public service trunking system
Inventor: NAZARENKO DIMITRI M
IPC: H04B7/15
Filed: 1988-10-13
Granted: 1992-07-21
Abstract: ABSTRACT OF TEE DISCLOSURE           A downlink between a communications dispatch console and a digitally trunked radio repeater system site controller efficiently transfers message data between the site controller and the console over a standard 9.2 kilobit per second landline.  A downlink trunking card identical in structure to trunking cards used in the preferred embodiment system for RF channel signal processing interfaces the site controller with the landline link.  A similar trunking card on the other side of the landline link interfaces the dispatch console processor with the landline link. Message protocol and format is translated between the site controller and the landline link and between the landline link and the dispatch console.  Data buffering at each end of the landline link maximizes data transfer rate over the landline, and in addition, a priority scheme insures that more important messages are transmitted over the downlink before less important messages.  Retransmit-until-acknowledged protocol is used to insure reliable message transfer -- and also to permit receiving units along the downlink to slow down transmitting units in order to avoid message traffic blockage.

Title: Hands-free telephone
Inventor: YOSHIDA IKIO
IPC: H04W88/02

Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE      In order to perform voice-switched telephoning, a  hands free  telephone  includes  a  speaker,   a microphone, a receive variable attenuator (R-ATT), a transmit  variable  attenuator  (T-ATT),  a  receive signal detector,  a transmit signal detector and an attenuation  control  circuit.   The  telephone  also includes an auxiliary control circuit which prevents the  output  of  the  transmit  signal  detector  from reaching the  attenuation control  circuit during a transient period between a call origination and the beginning  of  conversation.   During  the  transient period, only  the  speaker  is  enabled  to  output  a ringback tone therethrough.  When the output level of the transmit signal detector exceeds a predetermined level,  the  auxiliary  control  circuit  passes  the output  of  the  transmit  signal detector  to  the attenuation   control   circuit   to    start   the voice-switched  telephoning.    Once  the  auxiliary control circuit passes the output of the transmit signal  detector,  it  holds  this  state  until  the conversation finishes.

Abstract: CONTROL OF MULTIPLE FUNCTIONAL UNITS        WITH PARALLEL OPERATION IN A MICROCODED EXECUTION UNIT                      ABSTRACT To increase the performance of a pipelined processor executing various classes of instructions, the classes of instructions are executed by respective functional units which are independently controlled and operated in parallel.  The classes of instructions include integer instructions, floating point instructions, multiply instructions, and divide instructions.  The integer unit, which also performs shift operations, is controlled by. the microcode execution unit to handle the wide variety of integer and shift operations included in a complex, variable-length instruction set.  The other functional units need only accept a control command to initiate the operation to be performed by the functional unit.  The retiring of the results of the instructions need not be controlled by the microcode execution unit, but instead is delegated to a separate retire unit that services a result queue.  When the microcode execution unit determines that a new operation is required, an entry is inserted into the result queue.  The entry includes all the information needed by the retire unit to retire the result once the result is available from the respective functional unit.  The retire unit services the result queue by reading a tag in the entry at the head of the queue to determine the functional unit that is to provide the result.  Once the result is available and the destination specified by the entry is also available, the result is retired in accordance with the entry, and the entry is removed from the queue.
